Basic circuit calculations Flashcards
what is the calculation for apparent power
V*I
what is a capacitance
the electrical characteristic of a conductor
what’s effective value
a value of a sine wave alternating current needed to produce the same amount of heat as the value of the direct current
what’s capacitive reactance
an opposition to the change of voltage across an element
what is frequency
the number of wave crests that pass a given point in one second
what is impedance
a measure of the opposition to electrical flow
what’s the electrical characteristic of a conductor
Inductance causes voltage to be produced when it is cut or crossed by lines of magnetic flux inductance causes the current to lag the applied voltage
what is voltage measured from zero voltage to the maximum number of volts generated
peak voltage
what’s the amount of time for one complete cycle of oscillation to take place
period
what’s the electrical characteristic of a conductor
reactance
